Registro espacial 2D–3D para a inspeção remota de subestações de energia

Remote inspection and supervisory control are critical features for smart factories, civilian surveillance, power systems, among other domains. For reducing the time to make decisions, operators must have both a high situation awareness, implying a considerable amount of data to be presented, and minimal sensory load. Recent research suggests the adoption of computer vision techniques for automatic inspection, as well as virtual reality (VR) as an alternative to traditional SCADA interfaces. Nevertheless, although VR may provide a good representation of a substation’s state, it lacks some real-time information, available from online field cameras and microphones. Since these two sources of information (VR and field information) are not integrated into one single solution, we miss the opportunity of using VR as a SCADA-aware remote inspection tool, during operation and disaster-response routines. This work discusses a method to augment virtual environments of power substations with field images, enabling operators to promptly see a virtual representation of the inspected area's surroundings. The resulting environment is integrated with an image-based state inference machine, continuously checking the inferred states against the ones reported by the SCADA database. Whenever a discrepancy is found, an alarm is triggered and the virtual camera can be immediately teleported to the affected region, speeding up system reestablishment. The solution is based on a client-server architecture and allows multiple cameras deployed in multiple substations. Our results concern the quality of the 2D–3D registration and the rendering framerate for a simple scenario. The collected quantitative metrics suggest good camera pose estimations and registrations, as well as an arguably optimal rendering framerate for substations' equipment inspection.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCEMIG - Companhia Energética de Minas GeraisCNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo a Pesquisa do Estado de Minas GeraisTese (Doutorado)A inspeção remota e o controle supervisório são requisitos críticos para fábricas modernas, vigilância de civis, sistemas de energia e outras áreas. Para reduzir o tempo da tomada de decisão, os operadores precisam de uma elevada consciência da situação em campo, o que implica em uma grande quantidade de dados a serem apresentados, mas com menor carga sensorial possível. Estudos recentes sugerem a adoção de técnicas de visão computacional para inspeção automática, e a Realidade Virtual (VR) como uma alternativa às interfaces tradicionais do SCADA. Entretanto, apesar de fornecer uma boa representação do estado da subestação, os ambientes virtuais carecem de algumas informações de campo, provenientes de câmeras e microfones. Como essas duas fontes de dados (VR e dispositivos de captura) não são integrados em uma única solução, perde-se a oportunidade de usar VR como uma ferramenta de inspeção remota conectada ao SCADA, durante a operação e rotinas de respostas a desastres. Este trabalho trata de um método para aumentar ambientes virtuais de subestações com imagens de campo, permitindo aos operadores a rápida visualização de uma representação virtual do entorno da área monitorada. O ambiente resultante é integrado com uma máquina de inferência estados por imagens, comparando continuamente os estados inferidos com aqueles reportados pela base SCADA. Na ocasião de uma discrepância, um alarme é gerado e possibilita que a câmera virtual seja imediatamente teletransportada para a região afetada, acelerando o processo de retomada do sistema. A solução se baseia em uma arquitetura cliente-servidor e permite múltiplas câmeras presentes em múltiplas subestações. Os resultados dizem respeito à qualidade do registro 2D–3D e à taxa de renderização para um cenário simples. As métricas quantitativas coletadas sugerem bons níveis de registro e estimativa de pose de câmera, além de uma taxa ótima de renderização para fins de inspeção de equipamentos em subestações

How genealogy reveals the changing relationship between people and their use of recreational public space

The public space is and has been an integral part of communities for centuries. It serves as a convenient setting for a broad variety of leisure and recreational activities, as well as enhancing the image and perceived value of a community. Recreational public spaces provide a location for people to meet, relax, and exchange ideas. They can serve the needs and interests of all kinds of people, young and old irrespective of their cultural backgrounds. This report seeks to trace the genealogy of people and their use of recreational public space. Thus it uncovers the history of how space is perceived, interpreted and understood by people who live in Yeoville. It focuses on the understanding of space as an agglomeration of people, objects and events.The report also seeks to conceptualize people’s perception on the use of recreational public space and explore the changing relationship between people and their use of space in Yeoville. Through the process of perception we create a sense of place, i.e. a relationship within a specific context. If a place is memorable, it is because it carries perceptual attributes such as clarity, differentiation, uniqueness, structure and form. Planning practice seems to overlook the importance of incorporating genealogy into planning for diversified cultural communities. The use of narratives or storytelling can have a great significance for planners when planning for these communities. Identifying the core components of a Good City Form and the production of space, the paper goes on to connect these elements based Lynch’s theory of ‘Good City Form’ which was propounded in 1981 and also Lebfebvre’s theory on ‘The Production of Space’ (1991), translated from La production de l’espace(1974). Lynch’s Good City Form (1981) form the theoretical base for this report as his five performance dimensions are used to measure whether Yeoville does meet the criteria

Beyond the Banlieue: French Postcolonial Migration & the Politics of Sub-Saharan Identity

“Beyond the Banlieue: French Postcolonial Migration & the Politics of a Sub-Saharan Identity” details and historicizes the interstitial area between French state acculturation policies and the lived experience of Afro-French residents from 1945-2018. The project uses oral histories from Black communities in Paris to reveal a rich legacy of sociopolitical, economic and cultural efforts to navigate and negotiate this divide. These narratives offer an alternative perspective to prevailing scholarly and popular discourses emphasizing decline, resentment, intractability and rebellion as the defining features of French race relations in the late twentieth and early twenty-first century. This dissertation examines the attempts and attitudes of activists, entrepreneurs, artists, authors, teachers, youth and politicians to reclaim a largely untold history of the way that three generations of African migrants have contested the “invisibility” of race and the shortcomings of state policy to forge communities and multilayered identities in the postcolonial era. Interweaving the processes of migration and acculturation, this project mines the experiences of black diasporic populations in Paris over the past seventy years to reimagine the place and power of race in contemporary French history

Meeting Trees Halfway: Environmental Encounters in Theatre and Performance

abstract: How do trees (live and representational) participate in our theatrical and performed encounters with them? If trees are not inherently scenic, as their treatment in language and on stage might reinforce, how can they be retheorized as agents and participants in dramatic encounters? Using Diana Taylor’s theory of scenario to understand embodied encounters, I propose an alternative approach to understanding environmental beings (like trees) called “synercentrism,” which takes as its central tenet the active, if not 100 percent “willed,” participation of both human and non-human beings. I begin by mapping a continuum from objecthood to agenthood to trace the different ways that plants and trees are used, represented, and included in our encounters. The continuum provides a framework that more comprehensively unpacks human-plant relationships. My dissertation addresses the rich variety of representations and embodiments by focusing on three central chapter topics: the history of tree representation and inclusion in dramatic literature and performance; interactions with living trees in gardens, parks, and other dramatic arenas; and individual plays and plants that have a particularly strong grasp on cultural imaginaries. Each chapter is followed by one or more corresponding case studies (the first chapter is followed by case studies on plants in musical theatre; the second on performing plants and collaborative performance events; and the last on the dance drama Memory Rings and the Methuselah tree). I conclude with a discussion of how the framework of synercentrism can aid in the disruption of terministic screens and facilitate reciprocal relationships with trees and other environmental agents.Dissertation/ThesisDoctoral Dissertation Theatre 201

Ecology-based planning. Italian and French experimentations

This paper examines some French and Italian experimentations of green infrastructures’ (GI) construction in relation to their techniques and methodologies. The construction of a multifunctional green infrastructure can lead to the generation of a number of relevant bene fi ts able to face the increasing challenges of climate change and resilience (for example, social, ecological and environmental through the recognition of the concept of ecosystem services) and could ease the achievement of a performance-based approach. This approach, differently from the traditional prescriptive one, helps to attain a better and more fl exible land-use integration. In both countries, GI play an important role in contrasting land take and, for their adaptive and cross-scale nature, they help to generate a res ilient approach to urban plans and projects. Due to their fl exible and site-based nature, GI can be adapted, even if through different methodologies and approaches, both to urban and extra-urban contexts. On one hand, France, through its strong national policy on ecological networks, recognizes them as one of the major planning strategies toward a more sustainable development of territories; on the other hand, Italy has no national policy and Regions still have a hard time integrating them in already existing planning tools. In this perspective, Italian experimentations on GI construction appear to be a simple and sporadic add-on of urban and regional plans
